Though, I can still see them being tricky to get right, especially when trying to tune the power so that they're not so weak as to be useless and not so strong that you play with surfaces more than actual skills (Similar to how in ME3 the damage of combos was so high that actual skills and skill damage was irrelevant, it was all about proccing the combo damage)
What I think was very smart about them is D:OSs is that Larian took what is a fairly abstract aspect of RPG - status effects - and externalised them into the game map, and made them easy to interact with.
Oh, I have complaints aplenty about D:OSs combat, but in general it is a very fresh take and one worth pursuing and expanding on.
In BG3 though, I just found them intrusive rather than fun. Not that they couldn't get more AoE effects that get place on the map - I just didn't think Larian's guaranteed effect design gelled with will roll based nature of D&D.
